I'm facing with an issue with my Sannce N48PT. Looks like it provides no power to the POE cameras. Weird as they do work with Sannce N44SU nvr instantly. (had to replace that due to the ethernet port got faulty). The camera is a Sannce I41CC. Seller did not provide adapter so I had to purchase a 48V adapter 1.46A. No idea whats wrong. At the ethernet port there is no green/yellow light whatsoever. When I connect the ethernet cable from the modem to one of the camera port, it's start to blink. Is the unit faulty? Any suggestion would be appreciated.... Also tried to reset the cameras but it's impossible as I can't get them online....

Hi aqwer,

Did you just get that kit? If so perhaps time to return it and look for a better brand. ( Sannce / Annke - they're probablematic at times - some products they claim are PoE are what they call "sPoE" - or simplified PoE - also known as NOT PoE )

[ I can't even get their website up right now.. so not even able to see how they describe this product ]

Yes, I recently purchased it. If there is no solution at all, I will return it. The problem is that I still need an NVR which is compatible with the cameras. I could cry...

Did you get the cameras separately?

If you got them all from one place - and they're not working - then check the cables and bench test it. Try another cable you know is good.

I've got another Sannce NVR which came with 4 POE cameras, worked all good till, we had a nasty thunder storm and somehow the ethernet port for the modem died. (NVR still working perfectly with the cameras, but You can't go online) so Ithought,ok it's time for another, so I purchased an 8 channel one, same brand. What could go wrong... I've tried to investigate if the ports have power in by a multimeter and I got a big spark, so I guess it has. If I plug the cable which comes from the modem, to the camera ports all starts to communicate (green/yellow blinks)

Please check the specs here: (this is my previous nvr)

Is there any way to get a workaround on the faulty ethernet port(modem input)? I know there are many usb to ethernet adapter, however they required to install the driver. Is it possible to make it work on an NVR?

A standard POE device, the working voltage is 48V, and complies with the IEEE802.3 af/at standard. We looked up your product (I41CC ), it is not a standard POE device, the working voltage is 12V, they are called SPOE. It's an outdated technology,

The POE standard is 48 volts DC, but unfortunately some manufacturers make proprietary equipment that sends 12 or even 5 volts DC over ethernet, and they sometimes label those products POE as well. You'll also see passive adapters you can plug any arbitrary power supply into sometimes labeled as "POE injectors" when they're nothing of the sort.

Any major brand-name manufacturer should be correctly labeling their products, but if you're buying generic, imported, or unbranded products, you'd better read the specs to make sure it will work with standard POE equipment.
